The author was advised to abandon her visit to the city and she agreed to go back, the police officer said.

This is a dire, implicit warning to all Indians:

The protest at the airport was led by Imtiyaz Jaleel, a leader of All India Majlis-e-Ittehadul Muslimeen leader in Aurangabad.

Jaleel said her writings have “hurt” the religious sentiments of Muslims across the world. “We will not allow her to step on the soil of our city,” he said.

"Our city"? Since when did Mumbai become a Muslim city?

And, of course, hurting the feelings of Muslims is a valid enough reason for them to ban you from "their" cities. It's going to be a rude awakening for Muslims all over the globe when infidels start playing by the same rules.
